  1. this is a blog by fat lazy basement dwellers who can't fathom anyone playing a few hours of tennis without roids

    1. Definitely correct. Probably.

    2. ... and that is enough to prove the innocence of the entire tennis tours.

    3. Your gutter-mouthed comment only shows how uneducated and hateful you are, and it's not hard to guess the source of that hate. You have no love of tennis or concern for the integrity of the sport, only the conviction of a shallow bigotry that needs stay in a state of denial.

    4. If you think lance Armstrong was an anomaly and not the norm than I have a bridge to sell you.

  2. Good work. Nice to see facts, figures and data. What the hell are tennis journalists writing about? Why isn't this stuff reported? Shame on them.

  3. A recent documentary "Bigger Faster Stronger" reveals the extend of the steroid problem in the U.S. The former head of the United States anti doping agency says in this documentary over 2000 U.S athletes at all levels have had unusual or positive drug test results. And no one is doing anything about it, because of the money involved in elite athletics.
